Abstract

Described is a combination electrode friction chuck and stirrer assembly, which comprises in combination, (a) a hollow, cylindrical friction chuck body (10), which utilizes two o-rings (18,20) to retain an electrode therein, and (b) a stirrer body (12), connected to the base of the chuck body, said stirrer body comprising a hollow cylindrical member having two independent side walls (26,28) and an end wall (30), which includes a magnetic stirrer receptacle (32) therein. The side walls of the stirrer body provides some protection to an electrode contained therein, and the use thereof ensures that test samples being measured will be completely mixed. Due to the unique o-ring configuration, the chuck is self centering. Groove depth, chuck O.D., chuck inside diameter, o-ring inside diameter, o-ring durometer and o-ring cross section all influence the size of electrode cylinders that can be accepted as well as operating forces involved therewith.
